40-50 Irving St, San Francisco, CA 94122

The four-story, 11-unit multi-family residential building at 40-50 Irving Street in the Inner Sunset, owned by Chris and Tam Renee Mak, has undergone several significant renovations and maintenance work since its 1908 construction. Most recently, in 2023, the building experienced plumbing issues requiring a housetrap replacement after a violation was filed in April due to a clogged system and sanitary sewer problems.

The building has seen consistent maintenance and upgrades over the years, including a substantial $35,000 total remodel of kitchens and bathrooms in 2016-2017, installation of grab bars in 2013 to comply with ADA requirements, and kitchen renovations across multiple units. Recent concerns have been primarily related to waste management, with ten instances of overflowing city garbage cans reported between December 2024 and January 2025.

The building's safety systems have experienced occasional false alarms and smoke detector activations, though none resulted in injuries or actual fires. Historical records show various infrastructure improvements, including street space repairs in 2007-2008 and stair repairs in 2000. The property has maintained compliance with housing codes, with violations being promptly addressed and abated, including the 2023 plumbing issue which was resolved within one month.
